Description
Technical field
The present invention relates to a kind of sorting of fresh tea passes, complete equipment and system.
Background technology
Green tea processing technology generally comprises sorting, completes, kneads and drying, and the object wherein completed makes oxidizing ferment particularly polyphenol oxidase and peroxide enzyme deactivation fast, thus stop the oxidation of Tea Polyphenols (mainly catechin); Process of kneading is shaping on the one hand, makes water-removing leaves clasmatosis on the other hand, and tea juice overflows, and inclusion transforms further; Drying is also a kind of heat chemistry effect, and Main Function removes moisture further, forms fragrance simultaneously and promotes that the complicated catechin of ester type transforms to simple catechin further.Complete, knead and the combination of dry manufacturing procedure, define that the distinctive look of green tea is green, dense refreshing, the fragrant high qualitative characteristics such as fresh of taste, and these qualitative characteristics and the change of its quality component in process have much relations.
In the process completed and dry, all along with the change of catechin.Wherein catechin belongs to flavanols compounds, and the content in green tea is 12%-24%, is the important taste compound in green tea, has stronger convergence.In current tealeaves, explored catechin monomers and isomers mainly contain: nutgall catechin (GC), catechin (c), epigallocatechin (EGC), epicatechin (EC), Epigallo-catechin gallate (EGCG) (EGCG), L-Epicatechin gallate (ECG), nutgall catechin gallic acid ester (GCG), catechin and gallate (CG) etc.These catechins are extremely unstable in the process engineering of tealeaves, be easily oxidized, pyrolysis, a series of effect such as polymerization and conversion and its total amount is reduced, monomer ratio changes, and affects quality and the health-care efficacy of tealeaves.
Common stoving process is:
(1) complete: green tea tender leaf is put into green-keeping machine and completes, described in temperature when completing be 165 DEG C, the time is 4min;
(2) shaping: the tealeaves after completing is put into shaping machine and carries out shaping, temperature during described shaping is 80 DEG C, and machine speed is 175r/min;
(3) preliminary drying: the tealeaves after shaping is put into dryer and carries out preliminary drying, temperature during described preliminary drying is 115 DEG C, and preliminary drying time is 18min; During described preliminary drying, the leaf layer thickness of tealeaves controls at 2-2.5cm;
(4) dry: the temperature of dryer is down to 95 DEG C, dries, drying time is 25min; During described oven dry, the leaf layer thickness of tealeaves controls at 1.5-2cm.
In this course, completing of tealeaves is all arranged on 160 degrees centigrade, catechin wherein is easily oxidized, pyrolysis, a series of effect such as polymerization and conversion and its total amount is reduced, monomer ratio changes, and affects quality and the health-care efficacy of tealeaves.
Sorting refers in addition, and by the process that the tea stalk in the fresh tea passes of just having plucked, sandstone impurity are rejected, general employing at present manually carries out sorting, inefficiency, and can not realize the screening of automation.
